Homeland Security warns that US carriers are selling phones with compromised security

The Department of Homeland Security funded a research meant to investigate how safe are smartphones sold in the United States. Some of the research’s results were reported during a conference in Las Vegas this week.

The team found multiple vulnerabilities in devices from different manufacturers, and sources say that millions of customers are using compromised smartphones sold to them by Verizon, AT&T, T-Mobile, Sprint and other carriers and major retailers.
